I am coding for a mobile application and using stack exchange API 2.1. I am able to implement oauth and I have access token also.
Now I am trying to retrieve my profile information, like user_id, name etc. using /me, I am passing my access token here in query string, but it seems to add a 'key' when I hit run.
What is that key and how would I get it for my phone app. I tried using client_secret and they app key they provide you register your app, doesn't seem to give me any response.
